While she admits as the days at the Capitol will likely get longer, and depending on what committees she serves on, she may have to enlist a nanny to help. But she said it's important to make it work.

"There's generally been the expectation that women wait until they're done raising children to run for office," said Zwiener. "I don't think Ann Richards ran until she was in her late 40s or early 50s, and that's losing a lot of time."

And that's time that Zwiener doesn't want to waste as a mom or a public servant.

"I'm really pleased to be part of a generation who's not waiting anymore, and saying, 'Yeah, we can raise families and serve,'" she said. "And, in some ways, I think it's a strength because every time I look at my daughter I'm reminded of why I'm doing this. I'm doing this so every Texas child can have access to a great education, so every Texas child doesn't have to worry about access to health care, so that she can grow up and explore the same beautiful Hill Country I did as a kid."
